'.l'o all whom it may concern:

Be it known that I, EDMUND Hon-MANN, a citizen of the German Empire, and a resident of Stettin, in the Kingdom of lrussia, have invented certain new and useful Improvements in Horizontall Coke- Ovens; and I hereby declare the following to be a full, clear, and exact description ot the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invent-ion relates to improvements in horizontal coke ovens, and more particularly to coke ovens of the regenerative type in which the direction of the flow of the heating gases in t-he flues remains the same during the whole coking operation. In coke Iovens of this class vert-ical flues are provided in the partition walls of adjacent coking chambers, and to the said lines heating gases are supplied from below through suitable passages. In coke ovens of this class such as are now inuse the passages 'for admitting and distributing the gas to the flues are disposed in the same plane below the fines, and various means are provided whereby the heating gas is uniformly supplied to the gas nozzles in the `I'lue's.

The object of my improvements is to construct the passages through which the heating gases or the air for supporting combustion are supplied to the fines in the form of recuperators, for which purpose the said passages are arranged longitudinally ot the ssages through which the products of comustion escape from the flues, and the said passages are separated from each other by of the outgoing products of combustion can be transmitted to the heating gases or to the air for supporting combustion. Thereby the heating gases or t-he air for support-ing combustion are preheated by the outgoing products of combustion. In the preferred form one gas passage is used for supplying gas to two sets of ilues, whereby the oven becomes particularly simple in construction.

Preferably each gas admitting passage is divided into two see-tions byv a vertical partition provided cent-rally or" the oven, and each section is subdivided into two or more chamabove the other. When providing two chambers the heating gas .dowsat rst through the lower chamber trom the outer end to the inner end thereof, whereupon it passes to the upper chamber, or vice versa. From the gas admitting pas sage the gas is supplied to the gas nozzles provided within the lues through branch passages communicating with the said passages atV both sides thereof. The amount of the gas supplied to the lines can be regulated by means of regulating devices provided be tore or within the said branch passages.

For the purpose of explaining the invention 'several examples embodying the same have been shown in the accompanying drawings in. which the saine letters of reference have been used in all the views to indicate corresponding parts.

In said drawings Figure 1, ,is a vertical longitudinal section of an oven, taken partly (at the extreme left) through acoking chamber, on the line 1b 1" of Fig. 2, partly (toward the center of Fig. l) through the lues, on the line P la of Fig. 2, and partly (at the right) through line 1 1 of Fig. 2, Fig. 2, is a vertical crosssection of the oven taken at the left hand part on the line 2 2"l, and at the right hand part on the line 2 2 of F ig. 1, Fig'. 3, is a vertical longitudinal section of another construction of the oven, the left hand part of the figure being a section taken on the line fr f of Fig. 4, and the right hand part of the ligure being a section on the line ,3 3 of Fig. 4, the. oven being partly broken away at the left hand part, Fig. 4, is a Vertical crossseetion of a part of the voven shown in Fig. 3, the lefthand part of the figure being a section on the line 4 4", and the right hand part onthc line 4 4 of F ig. 3, Fig. 5,

1s a vertical longitudinal section of a furthe left hand part i ther example ot' the oven, of the ligure being a section on the line 5 5, and the right hand part on 1the line 5 5 of Fig. G, the oven being partly broken away at the left hand part, and Fig. 6, is a vertical cross-section of the oven shown in Fig. 5, the left hand part of the figure being a section on the line 6 6, and the right hand part a section on the line 6 6 of Fig. 5.

Referring particularly to the example illustrated in Figs. l and 2 of the drawings, my improved oven consists' of a` plurality of eoking chambers l arranged side by side and having their partition walls provided a coking chamber on the 4 for-the descending gases.

the outgoing products of combustion. The

assage 6 is dlsposed below the coklng chambei1 1 and parallel to the longitudinal axisof the oven, and its outlet 7 communicates with a regenerator not shown in the drawings, but

f the construction usual in ovens of the rel generative type. By a vertical partition 8 each passage 6 for theoutgoing products of combustion is divided into two sections. Beneath alternate passages 6 .gas admission passages A10 are provided which are divided e' into two sections by vertical partition walls each section of the gas inlet passage 10 is 9, and which are arranged parallel to the adjacent passages 6 and are separated from the latter by partitions 21 through which the heat of the outgoing Vproducts of combustion isk transmitted from the passages 6 to the passages 10.

' .In'the example shown in Figs. 1 and 2 the gas admitting passages 10 are located below the passages 6. By a horizontal partition 1,1

divided into two chambers located one above theA other and communicating with each other at theirvinner ends.I By branch passages 12 the upper chambers'are connected I with the nozzles 13 located" within the ascending sections 3 of the tlues 2'. If desired each section ofthe gas inlet passages 10 may be divided into three or more superposed chambersby a plurality of horizontal partitions which'are'alternately connected with eachother at their opposite ends, and in each case the aforesaid branch 'passages 12 communh .itewith the uppermost chamber.

In the operation of the coke oven, the

- heating gas (which maybe ltaken from an .therethroug combustion, the heat ofthe outgoing prodapparatus for separating theby-p oducts) is supplied at each side ofthe oven lthrough a main i14 and .branch pipes 15 to the lower chambers of the gas admitting passages 10,

Hows through. the Sallie in the direction of' the arrow, and .passes4 irito thel upper chambers ofV the channels 10 fronifwlhence it is supplied to the nozzles 13f'of the {lues 2 through` the branch passages 12.L

As the upper chambers of the gas admitting and distributing passages l0 are lobated directly below the passages 6 which are heated to a liigx temperature by the passage of the outgoing products of ucts of combustion is transmitted to the The amount of gas flowing. through the branch passages 12 to thenozzles 13 can be either located in the branch passages l2, or Within the upper chambers of the channels 10. In the latter case the said regulating devices consist of, slide valves or gates 16 formed of stone which are adapted to be pushed in front of the mouths of the branch. passages 12. In the example illustrated Vthe said valves which are preferably made of refractory material are adjusted from the outside through l (normally closed) peep holes 17 by means of rods. The said'peep holes sage 10, in' which case the passages 12 connect the lower chamber of the vsaid channel with the nozzles 13. In this construction of the oven the gas passes first through the upper chamber and .thereupon through the lower chamber of the passage 10. Below those passages 6 for the outgoing products gas admission channels 10, air admission passages 19 are provided which are parallel to the passages 6, and whichcommunicate with the tlues 2 through branch passages 20.

Each of the said air admission passages is yseparated from the passage 6 which is located above the same bya partition 22 which lpermits the transmission of the heat from lthe outgoing products of combustion to the air, so that the air for supporting combustion is preheated ina similar way to the heating gas.

T he ovn illustrated in Figs. Sand 4 is vsimilar in construction to that shown in Figs. 1 andi2. But it dili'ers therefrom in this respect, that the upper chambersof the.

- gas 'admission passages 10a are located within alternate passages 6 for the outgoing products of combustion. The air admission lpassages; 19B/ are disposed below those 'pas-A j. sages 6a which alternate with the passages ,6a inclosing the upper chambers of the gas admission passages l0. The passages 6a and 10l are separated from each other by parti# j tionv walls 21a through which heat mittcd from the passages 6a to the passages 10% and the passages 6 and 19a are separated from each other by partit-ion walls 22a through which heat is transmitted from the 1s transpassages 6L to the passages 19a. As shown in Fig. 4 the slide valves or gates 16a are j formed with inclined seating surfaces.: Each iflue 2 communicates with two passagesv 6a of combustion which are located between the alternate channels 6 disposed above the for the outgoingproductsof combustionA I through branch passages 5a. heatlng gases s o that the latter are preheated. I

In the example shown in Figs.l 5 and,

the upper chambers of the gas admission y passages 10b are provided, at the side of each controlled bv regulating devlces which are .combustion, and adjacent to the lower chambers of the said gas admissionpassages 10b air admission passages .19b .arel

located. From the passages 6" heat is'tgnnsmitted tothe'passages 10and 19 through partition'walls 21b and 22 respectively.

Byarranging the passages for the admission of the .heating gases and the air for sup orting combustion in the manner de` scri d` the 'heating gases and the air for 4`supportin combustion are eil'ectually 'preheated, w ereby the eliiciency of the coke 10 oven is increasedr The subdivision of the gas supply passage (10, 10'?, or 10") into two compartments or """chanbers by the partition 11, 1s an impor;

` tant-feature Aof my invention. It will be observed that the gas -inlet 15 is located in one of said'compartments, at the end op osite to that at which the two com artments communicate with eachother. xcept for this communicating cha'nnel at one end, the

partition '11 is im erforate. The branch passages 12 lead rom the compartment which has no direct connection with the inlet 15. Thus, in,order to reach even the first, of the branch passa es 12, the gas must 2s travel the full length o the supply passage ('10, 10l or 10b), and'in this manner I in.- sure a thorou h'and practically uniform preheating of t e gas.
